shinymedia is a Python package that provides Shiny UI controls for recording and playing back media.

At this time it includes two components:

You can see these two components in action together in our live demo (source code).

Recording video with input_video_clip

This component allows you to record video clips using attached cameras. Press the Record button to start recording, and press Stop to stop. The recorded clip will be sent to Shiny as a data URI in whatever video format the browser supports.

The example below lets you see what the component looks like, although it won’t actually do anything with the recorded video in this static document.

from shinymedia import input_video_clip

input_video_clip(
  "clip1",
  video_bits_per_second=256000,
  audio_bits_per_second=64000,
  style="width: 400px; max-width: 100%;",
)
  • Camera
  • Microphone

Visualizing audio with audio_spinner

Plays audio with a visualization that spins and pulses in time with the audio signal.

Click the icon to play.1

from shinymedia import audio_spinner

audio_spinner(
  src='mp3/essaisurlesrevolutions_00_chateaubriand_64kb.mp3',
  width="125px",
  height="125px",
  autoplay=False,
)

There are many options for customizing the appearance and behavior of the spinner. Here is an example with a dark background, faster rotation, more blades, and a thinner stroke. See the reference docs for more information on these and other options.

from shinymedia import audio_spinner

audio_spinner(
  src='mp3/essaisurlesrevolutions_00_chateaubriand_64kb.mp3',
  class_="bg-dark rounded-3 mx-auto",
  width="125px",
  height="125px",
  autoplay=False,
  rpm=33,
  blades=8,
  gap=0.2,
  stroke=1,
  steps=5,
)
